What is the shear force of a fluid (velocity ( vec{u} )) near the wall for a moving wall (velocity ( ( overrightarrow{u_{wall}} )))?

Question

What is the shear force of a fluid (velocity  ( vec{u} )) near the wall for a moving wall (velocity ( ( overrightarrow{u_{wall}} )))?

TuteeHUB · Accepted Answer

(  vec{F}=-  mu  frac{  vec{u}-  overrightarrow{u_{wall}}}{  Delta y}  )

TuteeHUB · Answer

(  vec{F}=-  mu  frac{  vec{u}}{  Delta y}  times area  )

TuteeHUB · Answer

(  vec{F}=-  mu  frac{  vec{u}-  overrightarrow{u_{wall}}}{  Delta y}  times area  )

TuteeHUB · Answer

(  vec{F}=-  mu  frac{  vec{u}-  overrightarrow{u_{wall}}}{  Delta y}  )

TuteeHUB · Answer

(  vec{F}=-  mu  frac{  vec{u}}{  Delta y}  )
